Description

Technical Field

[0001] The utility model relates to the technical field of elevator bolt equipment, in particular to an elevator bolt provided with a guide structure. Background Art

[0002] Elevator bolts are fasteners specifically designed for the elevator installation industry. They are widely used in elevator rails, brackets, supports, mechanical equipment, and in the installation of building components that withstand vibration and heavy loads. They are an indispensable component for the normal operation of elevators and play a vital role in ensuring their safety and stability.

[0003] For example, the utility model patent disclosed in the publication number CN219045510U is a bolt provided with a guide structure, which belongs to the technical field of mechanical parts. The key points of its technical solution include a bolt body, the bolt body including a first stud and a second stud fixedly connected to the bottom of the first stud, the upper end face of the first stud is fixedly mounted with a bolt head; a first guide nut, the first guide nut is movably mounted on the outer side walls of the first stud and the second stud, the outer side wall of the second stud is movably sleeved with a second guide nut, so that when the bolt body is used to punch a hole, the bolt head is rotated and the bolt body is rotated to screw it into the fixed object. The first guide nut and the second guide nut have a guiding effect on the bolt body, so that the bolt body is vertically screwed into the fixed object along the first guide nut and the second guide nut, preventing the bolt body from drilling the hole off-center, thereby avoiding damage to the bolt.

[0004] Although the above-mentioned bolts can limit the fixed objects, it is not convenient to seal and protect the nuts after the above-mentioned bolts are limited. At the same time, it is not convenient to pre-tighten the two sides of the limit, which reduces the stability of subsequent locking. Therefore, an elevator bolt with a guide structure is urgently needed to solve the above-mentioned problems. Utility Model Content

Six groups of positioning blocks 52 are equidistantly provided on the upper end surface of the displacement limiting chuck 51.

[0030] The threaded shaft 21 is threadedly connected to the inner end surface of the hexagonal insert 23 through the threaded groove 25, and the sealing cover plate 53 is sealed and clamped with the limiting nut 3. After the two sets of threaded shafts 21 are fixed on the hexagonal insert 23, they can be threadedly connected to the threaded groove 25 to improve the stability of the hexagonal insert 23.

[0031] The bolt 24 is threadedly connected to the limiting nut 3, and the sealing cover plate 53 is adapted to the threaded guide groove 26 through the threaded shaft 54 ​​and then threadedly connected to the bottom of the bolt 24.
